  1. Backgrounds Information:progress Roger Barlow and Dave Bailey (mostly Dave’s work)

  2. PVSS Set up system at Manchester • Makes development easier • Working remotely at CERN is possible but painfully slow • Learning – will go on course when available • Set up duplicates of LHCCOM and LHCBBM

  3. Just to show… Collimator position with trend lines Working now on an overview panel – using CAD drawing of the beamline to integrate the “expert” panels. Will add ‘correct’ position marks when we know what they are

  4. And also… from PAC09 SIMULATION OF THE LHC COLLIMATION SYSTEM USING MERLIN A. Toader∗ , R. Appleby, R. Barlow, H. Owen, S. AlShammari University of Manchester & The Cockcroft Institute, United Kingdom Abstract The LHC Collimators are designed to remove halo par- ticles such that they do not impinge onto either detectors or other vulnerable regions of the storage ring. However, the very high 7 TeV energy means that their design is critical, as is the modelling of the absorption, scattering and wakefield effects upon the passing bunches. Existing simulations are performed using Sixtrack and K2. We report preliminary results using the MERLIN code, which allows a fuller description of the scattering and wakefield processes, and in principle other physics processes.

  5. More questions • Are the vertical collimator positions available? • Are there other projects we should be running to make datapoints available? • Are there any diagrams of BLS etc? Would be useful to know the layout in order to make sensible panels. • Is there documentation on which datapoint to read out to get rates etc?

  6. Future DB and RB will be out for the Wed-Fri part of this meeting Further trips planned (June 15-19 for RB) short and longer term
